How can I change “Register” Button to display “Home” when user logged in

I looked around the forums but could not find this question. I currently have the latest version of wordpress and buddypress installed and I am working with the Genesis Framework. They sent me over here for my question…

All I want to do is sub out the Register button with a Home button when the user is logged in. Currently it redirects the user to the home page if they are logged in, but this is misleading and unnecessary.

I am not sure really sure where to start, but essentially something like this has to placed somewhere in the buddypress directory…..right?
